UK orders probe into Thatcher link to Operation Blue Star

It has been claimed that Margaret Thatcher's UK government helped plan Operation Blue Star

British Prime Minister David Cameron has directed his Cabinet Secretary to establish the facts behind claims that Margaret Thatcher's government may have helped Indira Gandhi plan Operation Blue Star in 1984.

Labour MP Tom Watson and Lord Indarjit Singh had demanded an explanation after recently declassified documents indicated that Britain's Special Air Service (SAS) officials had been dispatched to help India on the planning on the raid of the Golden Temple to flush out militants from the shrine, an operation left more than 1,000 people dead.

"These events led to a tragic loss of life and we understand the very legitimate concerns that these papers will raise.

"The Prime Minister has asked the Cabinet Secretary to look into this case urgently and establish the facts," a UK government spokesperson said in a statement.

"The PM and the Foreign Secretary were unaware of these papers prior to publication. Any requests today for advice from foreign governments are always evaluated carefully with full Ministerial oversight and appropriate legal advice," he added.

The documents being referenced were released by the National Archives in London under the 30-year declassification rule as part of a series over the New Year.

A letter marked top secret and personal dated February 23, 1984, nearly four months before the incident in Amritsar, titled 'Sikh Community', reads:

"The Indian authorities recently sought British advice over a plan to remove Sikh extremists from the Golden Temple in Amritsar.

"The Foreign Secretary decided to respond favourably to the Indian request and, with the Prime Minister's agreement, an SAD (sic) officer has visited India and drawn up a plan which has been approved by Mrs Gandhi.

"The Foreign Secretary believes that the Indian Government may put the plan into operation shortly."
